Add user-space networking stack API (usrsock) User-space networking stack API allows user-space daemon to provide TCP/IP stack implementation for NuttX network. Main use for this is to allow use and seamless integration of HW-provided TCP/IP stacks to NuttX. For example, user-space daemon can translate /dev/usrsock API requests to HW TCP/IP API requests while rest of the user-space can access standard socket API, with socket descriptors that can be used with NuttX system calls.

If dynamic connections allocation is enabled, more connections may
be allocated at a later time, as the system needs them. Else this
will be the maximum number of connections available to the system
at all times.

When set to 1 a new connection will be allocated every time,
and it will be free'd when no longer needed.
Setting this to 2 or more will allocate the connections in
batches (with batch size equal to this config). When a
connection is no longer needed, it will be returned to the
free connections pool, and it will never be deallocated!

This commit adds an as-of-yet untested implemented of UDP write buffering. Squashed commit of the following: net/udp: Address most of the issues with UDP write buffering. There is a remaining issue with handling one network going down in a multi-network environment. None of this has been test but it is certainly ready for test. Hence, the feature is marked EXPERIMENTAL. net/udp: Some baby steps toward a corrected write buffering design. net/udp: Remove pesky write buffer macros. Eliminate trailing space at the end of lines. net/udp: A little more UDP write buffering logic. Still at least on big gaping hole in the design. net/udp: Undefined CONFIG_NET_SENDTO_TIMEOUT. net/udp: Crude, naive port of the TCP write buffering logic into UDP. This commit is certainly non-functional and is simply a starting point for the implementatin of UDP write buffering. net/udp: Rename udp/udp_psock_sendto.c udp/udp_psock_sendto_unbuffered.c.

These tiny nodes are used as "containers" to support queuing of
UDP write buffers. This setting will limit the number of UDP write
operations that can be "in-flight" at any give time. So a good
choice for this value would be the same as the maximum number of
UDP connections.

write buffer logic and do not want to get overloaded with other
network-related debug output.
